ATA6617 - EK
The development board for the ATA6617 is shipped with the default jumper settings and all
accessories required for immediate use.
The IC mounted on the board is pre-programmed with a firmware in order to test and to under-
stand the basic functions directly on the board. After correctly connecting an external 12V DC
power supply between the terminals “+” and “-”, the LIN SBC is in Fail-safe Mode. A regulated
5V DC voltage, provided by the internal voltage regulator supplying the internal microcontroller,
can be measured at the PVCC jumper. After the power is supplied to the microcontroller, the
microcontroller switches the LIN SBC to Normal Mode by setting the EN pin to high (ENABLE
jumper), and starts to trigger the integrated window watchdog. The system is now ready for data
transmission via the LIN bus. Signals fed in at the TXD pin are visible on the LIN bus, and sig-
nals fed in on the LIN bus are visible at the RXD pin. In Normal Mode, the current consumption
is approximately 3 mA and the following voltages and signals can be seen at the corresponding
pins.
